Abstract
Disclosed are embodiments of a novel type of wave-powered propulsion adapted for use by buoyant vessels in order to provide or supplement their self-propulsion. An approximately vertical and semi-cylindrical propulsive shroud attached to a vessel interacts with a wave motion at and below the vessel in order to impart a thrust to the vessel.
Claims19
A buoyant apparatus, comprising:
- a wave energy converter comprising an upper bulbous portion fluidly coupled to a lower tubular portion along a longitudinal axis;
- and
- a shroud attached directly to the upper bulbous portion of the wave energy converter, wherein the shroud only partially laterally surrounds the wave energy converter around the longitudinal axis.
A buoyant apparatus, comprising:
- a first chamber;
- a tube with a first end and a second end, wherein the first end is fluidly coupled to the first chamber;
- a second chamber coupled to the second end of the tube;
- and
- a shroud coupled to at least one of the first chamber or the second chamber, wherein the shroud wraps partially around a longitudinal axis of the buoyant apparatus.
